CTA (Cross Traffic Alert)*
CTA (Cross Traffic Alert) is a driver aid
intended to warn about crossing traffic when
the car is reversing. CTA is a supplement to
BLIS (p. 257).
Activate/deactivate CTA
CTA is activated when the engine is started.
This is confirmed by the indicator lamps in
the door panels flashing once.
In cars equipped with parking assistance (p.
245), the CTA function can be deactivated/
activated with the parking assistance On/Off
button.
On/Off for parking assistance and CTA sensors.
CTA itself can be deactivated in the MY CAR
menu system as follows:
•
Go to
Settings Car settings BLIS
Cross Traffic Alert and deselect. The
CTA function is then deactivated. BLIS
remains activated.
WARNING
CTA is a supplementary aid and does not
work in all situations.
CTA is no substitute for a safe driving style
and the use of rearview and door mirrors.
CTA can never replace the driver's respon-
sibility and attention - it is always the driv-
er's responsibility to reverse in a safe man-
ner.
When CTA operates
Principle for CTA.
CTA supplements the BLIS function by being
able to see crossing traffic from the side dur-
ing reversing, such as when reversing out of a
parking space.
CTA is primarily designed to detect vehicles.
In favourable conditions, it may also be able
to detect smaller objects, such as cyclists
and pedestrians.
CTA is only active during reversing and is
activated automatically when reverse is
selected at the gearbox.
•
If CTA detects something approaching
from the side, an acoustic warning signal
sounds. The signal comes from either the
left or the right speaker depending on
which direction the approaching object is
coming from.
•
CTA also warns by illuminating the BLIS
lamps.
•
An additional warning is provided in the
form of an illuminated icon in the display
screen's PAS graphics (p. 245).
Limitations
CTA does not perform optimally in all situa-
tions, but has a certain limitation - for exam-
ple, the CTA sensors cannot "see" through
other parked vehicles or obstructing objects.
Here are some examples of when CTA's "field
of vision" may be limited from the beginning
and approaching vehicles cannot therefore be
detected until they are very close:
